Motional EMF Below is a rectangle that is being pulled into a magnetic field as shown. The rectangle has a height of h = 0.400 m and is being pulled to the right with a velocity of v = 188.0 m/s. This magnetic field starts where shown, so the left most side of the rectangle has no magnetic field. There is 1 loop with a total resistance of R = 15.40 Ohms. The magnetic field has a magnitude of B = 34.0 mT. That means as the loop moves to the right, the magnetic flux inside the loop is increasing.
